    I’ll have a stab at explaining, forgive my poor grammar. The 'flow temperature' is the temperature your boiler heats up the water to before sending it off to your radiators. Most gas boilers are set up to operate at what is called 80/60 flow and return temperatures. This means the boiler heats up the water (called ‘the flow’) to 80°C. The water returns to the boiler after travelling around all your radiators (called ‘the return’) at 60°C, having given off 20°C to the room.

    However 80/60 flow and return temperatures are too high for a condensing gas boiler to achieve the A-rated efficiencies shown 'on-the-box'. It is a little know fact that modern boilers have a variable efficiency between A-E, in other words they are not A-rated out of the box. Studies have found most to be C-E-Rated in the home, equivalent to just 75-85% efficiency.

    Your installer should have reduced the flow temperature to give the boiler a chance to run in what is known as 'condensing mode' as much as possible. This is when it can recover the heat that was previously lost through the flue on old style boilers.

    At 70/50°C the boiler will start to operate in condensing mode. Only when the flow temperature is 60°C or lower will the boiler recover enough heat to reach its higher efficiency potential.

    Like camping... but in a laboratory! ?

    #ClinicalCamping  ?

     

    Which reminds me... I must hoover my lawn before we go off proper camping in France in 10 days time!  ?

     

     

    Enjoy.  ??

    Going out bush for a couple of weeks in October, this place is on the water not too far from home.

     Have journey times decreased to Aus? I thought they were about 23 hours? Or was that with change of flights somewhere?

    Best I could do was 21 hrs Brisbane to London with Emirates or Singapore. The problem with Qantas is their main routes are Sydney and Melbourne meaning if you’re flying from Brisbane there’s a 5 to 6 hour wait for the connecting flight. Total flying time is 16 1/2 hrs to Perth and 4 1/2 hrs Perth to Brisbane. We’ve had big waits in London loading the commonwealth games bikes went an hour over and then another hour sitting in the plane waiting for a takeoff slot.
